Add Configuration Management Tool (tbd-cfg)

Overview

This PR introduces a new configuration management tool (tbd-cfg) that integrates with our existing infrastructure as code system. The tool provides Ansible integration and shares state management with tbd-iac, enabling unified infrastructure and configuration management.

Key Features

• Ansible playbook execution and validation
• Shared state management with tbd-iac
• TOML-based configuration files
• Command-line interface with apply, validate, and import commands
• Variable injection and environment targeting
• Shell script provider support (scaffolded)

Implementation Details

Core Components

• State Management: Created StateAdapter to interface with tbd-iac's state system
• Ansible Integration: Implemented AnsibleWrapper for playbook execution and validation
• Configuration: Added TOML-based config system with provider-specific implementations
• CLI: Built command structure using clap with support for multiple operations

Example Configuration

name = "web-server"
target = "dev"
provider = { type = "ansible", playbook = "web.yml", inventory = "dev.yml" }
variables = { port = 80, domain = "example.com" }

Testing

• Unit tests for core components
• Integration tests with Ansible
• CLI parsing tests
• State management tests

Usage

# Apply configuration
tbd-cfg apply -c web-server.toml -t dev --vars '{"domain": "prod.example.com"}'

# Validate configuration
tbd-cfg validate -c web-server.toml

# Import existing Ansible playbook
tbd-cfg import -p playbook.yml -i inventory.yml -n web-setup

Development Details

• Uses Task for automation and development workflows
• GitHub Actions for CI/CD
• Semantic versioning and release management
• Integration with existing tbd-iac state system

Future Work

• Add more comprehensive provider validations
• Implement shell script provider
• Add state migration capabilities
• Enhance documentation
